Can the series folder include both single issues and TPBs? When I filter for series type I only see sigle issues in one line and TPBs in another.
The series folder groups your issues based on what is filled in the “Series” field of each issue.
Does that help explain what is going on for you?
I think so. So if I wanted them all to appear in the same line, the TPBs and the single issues would all need to have the same info in the series field, correct?
That would put them in the same Series folder, indeed. Try it with one to see if you like the result!
